The C-250 allows single line telephones or a
telephone system to share a phone line with a
single Viking entry phone. Tenants may answer
an entry phone call, converse with the visitor
and let them in with a touch tone command.
The C-250 also has a built in five number dialer
to make an outside call if there is no answer on
the inside phone. If the outside call is busy or
ring no answer, the C-250 can call up to four
more numbers.
The C-250 provides a “Call Waiting” tone when the phone line is in use. Tenants may
also call out to the entry phone for monitoring purposes.

The speed dial number stored in location #00 is the first outside number that will be dialed if the door phone goes off
hook and the house phone does not answer within the ring count set by location #44. Additional speed dial numbers
will be dialed if there is no answer or a busy at the first number. Each number is called only once. If all numbers are
called without an answer, the C-250 will generate a CPC signal and then a busy signal will be sent to the door phone.
To clear a speed dial number position, simply enter a # and the location number (00 to 04), without any preceding numbers. If no numbers are programmed, the C-250 will only call the house phone.

Set DIP switch 3 on the front of the C-250 to the ON position. Come off hook with the house phone and 2 beeps
will be heard signaling that the C-250 is in the programming Mode. When finished programming, hang up the phone
and set DIP Switch 3 to the OFF position.
1. Local Programming
Set DIP switch 1 on the front of the C-250 to the ON position. Call into the unit from a remote touch tone phone.
After the incoming ring count is up (factory set to 10), the C-250 will answer the line and beep 1 time. Enter Q followed by the 6-digit security code (factory set to 845464). Two beeps will be heard signaling that the C-250 is in the
programming mode.
2. Remote Programming with the Security Code
Set DIP switches 1 and 3 on the front of the C-250 to the ON position. Call into the unit from a remote touch tone
phone. After one ring, the C-250 will answer the line and beep 2 times signaling that the C-250 is in the programming mode. When finished programming, hang up the phone and set DIP Switch 3 to the OFF position.
3. Remote Programming without the Security Code
F. Maximum Call Time (Memory Location #42)
The Maximum Call Time can be used to cut off a call that has rolled over to an outside number. The timer starts as soon
as the C-250 is done dialing each number. If the call lasts longer than the time programmed, the phone line will be
dropped and a busy signal will be sent to the entry phone. This is useful if a standard telephone is being used for an
entry phone and the handset is accidentally left off hook. This one digit number can range from 1 to 9 minutes or enter
0 for 30 seconds. To disable this feature enter #42 without any preceding digits. The factory setting is 3 minutes.
G. Maximum Ring Time (Memory Location #43)
After the C-250 dials an outside number, it listens to the phone line for busy, ringing, or someone answering at the other
end. The Maximum Ring Time is used to limit this process in the event that the C-250 cannot determine if the call has
been answered. If the C-250 cannot determine that the call has been answered within the Maximum Ring Time, the line
will be disconnected and the C-250 will go onto the next speed dial number. This two digit number can range from 01
to 59 seconds and can be disabled by entering #43 without any preceding digits. As a general rule, allow 6 seconds for
each ring you desire at the distant phone. The factory setting is 30 seconds or about 5 rings.
H. Security Code (Memory Location #47)
The security code must be 6 digits long and cannot contain a “Q” or “#”. The factory default code is “845464” and can
be changed in programming by entering 6 digits followed by “#47”.
D. Door Strike Activation Time (Memory Location #40)
The value stored in the Door Strike Activation Time is the amount of time the door strike relay will be energized after a
correct touch tone command is entered or the trigger input is activated. This two digit number can range from 01 to 99
seconds, or enter 00 for 0.5 seconds. The factory setting is 5 seconds.
E. Door Strike Command (Memory Location #41)
The one or two digit code stored in the Door Strike Command is the touch tone command that the person being called
must enter on their touch tone phone in order to actuate the door strike. The code can contain the numbers 1 to 9, 0,
Q, # or any two digit combinations. To disable this feature enter #41 without any preceding digits. The code must be
entered while the house phone or the remote phone is connected to the door phone.
The C-250 determines which direction the touch tone is coming from and only responds to touch tones from the called
phone. Because of this, single digit codes must be a minimum of 100 msec in duration. Some cell phones can only produce fast touch tones (< 100 msec). If using one of these phones, program a two digit Door Strike Command. When
two digits are programmed, the entry phone will be dropped after the first digit, so the C-250 can be sure the second
digit is coming from the called phone. With a two digit code, the minimum duration of the tones can be as low as
50msec. The factory setting is 6.
I. Ring House Phone Count (Memory Location #44)
When the door phone comes off hook, the C-250 will start ringing the house phone. The number of times the house
phone will ring is stored in location #44. This value can range from 1 to 9, if blank or 0 is entered, the C-250 will skip
ringing the house phone and immediately start calling the programmed phone numbers. This feature is useful when the
user is not at home and they want the fastest connect time to their cell phone. There is also an operational command
of QQQ (see Operation section B) and a trigger input (see section N, DIP switch 2) that can be used for immediate call
forwarding. The factory setting is 4.
J. Incoming Ring Count (Memory Location #45)
The 2 digit number in this location determines how many times a call coming in from the phone line will ring the house
phones before the C-250 answers the call. This number can range from 01 to 99, if blank or 00, the Auto Answer feature of the C-250 will be disabled. The factory setting is 10.
K. Ignore Touch Tones for Programming Entry Phone (##1)
This feature is useful if you have a entry phone that requires touch tone programming and can answer a ringing line
after 1 ring. All Viking Handsfree Entry Phones have this capability. After entering the programming mode, if ##1 is
entered, the C-250 will send a ring signal to the entry phone port. If the device on that port answers the line, the C-250
will connect it to the calling device (local or remote). If the entry phone does not answer, 3 beeps will be heard and the
C-250 will stay in the programming mode. Once connected to the door phone, the C-250 no longer reacts to touch tones
(except to reset the 20 second programming timer in the remote programming mode). In the remote programming
mode, if the 20 second programming timer elapses, the C-250 will hang up. In any of the other programming modes,
the timer is disabled and the C-250 only watches for the door phone to hang up.

L. “No CO” Mode (Q0,Q1)
When enabled, this mode allows the C-250 to be used in installations that do not have an incoming phone line. In this
mode, the house phone is connected directly to the internal artificial line. When the house phone comes off hook, the
door phone will start to ring. If the door phone has auto answer, the person in the house can monitor any outside activity. Door phone calls are handled the same as in the normal mode except it will not roll over to the phone line if there
is no answer at the house phone. To enable this mode, enter “
Q1” when in programming. To cancel the “No CO” mode,
enter “Q0”.
M. “Door Bell” mode (Q2,Q3)
If the door strike relay is not being used, it can be configured to operate a door bell. When in this mode, the door strike
relay will actuate whenever the door phone goes off hook. Connect the door bell or chime (and power supply) to the
normally open door strike contacts. The door strike relay will energize for a fixed time period of 1 second. To enable this
mode, go into programming and enter “
Q3”. To cancel the “Door Bell” mode, enter “Q2”.
N. Ring Pattern (Q4,Q5)
In the factory setting (Q4), the C-250 will ring the house phones with a double burst pattern when the door phone goes
off hook. This is done so that the person in the house can tell the difference between a visitor at the front door and a
regular phone call. In a few instances the double burst pattern may not be detected by some cordless phones. If this is
the case, go into programming and enter “Q5”. This will cause the C-250 to send a single burst pattern when the door
phone goes off hook. To go back to the double burst pattern, go into programming and enter “
Q4”.
O. Remote Door Strike Actuation (Q6)
The door strike relay on the C-250 can be actuated remotely without the C-250 initiating the call. To do this, dip switch
1 must be in the ON position and a value must be entered in the Incoming Ring Count location #45. From the remote
location, call into the C-250. After it answers, enter a “
Q” followed by the 6 digit security code. Wait for the 2 beeps and
enter “Q6”. After a short pause, the door strike relay will actuate for the programmed amount of time in the Door Strike
Activation Time position #40.

DIP Switch 3 in the ON position is used to gain access to the programming mode without needing a security code.
When the house phone goes off hook, two beeps will be heard signaling that the C-250 is ready for programming
commands. If a call comes in and the auto answer feature is also enabled (DIP Switch 1 ON), the C-250 will answer
the call on the first ring and send 2 beeps. When in the off position, the security code in position #47 has to be used
in order to enter programming. This switch needs to be off for normal operation. The factory setting is OFF.

When the entry phone goes off hook, the house phones will ring with a distinctive double ring cadence to identify it is
a entry phone call (programmable to a single ring cadence. The number entered into programming position #44 determines how many times the house phone will ring from an entry phone call before the call is forwarded using the auto
dialing numbers. If no numbers are programmed, the C-250 will send a CPC signal to automatically hang up the entry
phone. All Viking hands free phones are able to detect the CPC signal and hang up. If the C-250 senses that the entry
phone has not dropped off, it will send a busy signal. If auto dial numbers are programmed, it will dial the first one and
watch for a busy or no answer for the duration of the Maximum Ring time. If this time elapses and the C-250 has not
determined the call has been answered, it assumes that the call was not answered and goes on to the next speed dial
number. If all numbers are called without an answer, the C-250 will send a CPC signal to hang up the entry phone. The
Maximum Call Time is started as soon as the C-250 is done dialing each number. If this timer elapses, that call is terminated and no further numbers are dialed.
B. Immediate Call Forward
The entire sequence of the house phone ringing when the entry phone goes off hook can be skipped. This is useful if
the user will not be at home and wants the C-250 to skip ringing the house phone and immediately forward all entry
calls to the programmed phone numbers. There are several ways to do this. The first is to clear the house phone ring
count or set it to 0 in programming position #44. This can only be done in the programming mode, but can be done
locally or remotely if auto answer (DIP Switch 1) is on. The second way is to go off hook with any house phone and
enter “
QQQ”. This places the C-250 in the Immediate Call Forward mode. With this mode enabled, each time the house
phone goes off hook, a single beep will be heard in order to let the user know that this mode is on. To cancel the
Immediate Call Forward mode, pick up the house phone and enter “###”. Two beeps will be heard letting the user know
the Immediate Call Forward mode has been cancelled. These immediate call forward commands must be entered within 5 seconds of off hook. The third and final way is to provide a contact closure across the trigger input (DIP switch 2
must be ON).
C. Monitoring or Receiving Door Phone Calls
If the tenant wants to monitor the entry phone, they can pick up any phone in the house and hook flash within 5 seconds. This will cause the C-250 to ring the entry phone up to 5 times. Hook flashes after the 5 second time out will be
passed along to the CO line. This is useful for using standard CO call waiting features. If the tenant is on an outside
call, and the entry phone comes off hook, a call waiting tone will be heard every 12 seconds. The tenant can then hook
flash to put the CO call on hold and connect to the entry phone. When the conversation with the person at the door is
done, the tenant can return to the original caller with another hook flash. If using a 2 digit door strike code, the entry
phone will be dropped after the first digit.
Dip Switch 1 enables the auto answer feature. When in the ON position, the C-250 will answer an incoming call after
the number of rings programmed into location #45. If position #45 is cleared, or contains 00, the C-250 will not
answer the line. If this feature is enabled, there cannot be anything else on the phone line that could answer the call
before the C-250 such as an answering machine. If security is an issue, it is best to not allow remote programming
and leave DIP Switch 1 in the OFF position. The factory setting is OFF.

DIP Switch 2 determines the operating mode of the Trigger Input. When DIP Switch 2 is OFF, a momentary closure
connected to the trigger input will cause the Door Strike relay to actuate for the programmed amount of time in location #40. If DIP Switch 2 is in the ON position, the Trigger input now controls whether or not the house phone will
ring when the door phone goes off hook. If the trigger input is open, the house phone will ring for the number of
times programmed in location #44. If the trigger input is closed, the C-250 will skip ringing the house phone and go
right to calling the preprogrammed phone numbers. This Trigger Input mode is useful if you want to control the operation of the C-250 by some other piece of equipment such as a phone system placed in the night mode, a clock
controlled relay or a toggle switch. The factory setting is OFF.

The C-250 has a Trigger Input for an external Postal Lock switch, or a Request to Exit (REX) switch. The switch must
have a momentary, normally open contact. Once the C-250 detects a contact closure on terminal positions 8 and 9, the
door strike will be energized for the amount of programmed Door Strike Activation Time. If the contact is still made after
the programmed time is up, the C-250 will re-energize the door strike relay and go through another Door Strike timing
cycle.
If DIP Switch 2 is in the ON position, the Trigger Switch input now controls whether or not the house phone will ring
when the entry phone goes off hook. If the Trigger Input is shorted, the house phone ringing will be skipped (Immediate
Call Forward Mode), if open, the C-250 will ring the house phone when the entry phone goes off hook. The touch tone
command
QQQ overrides the status of the Trigger Input when DIP Switch 2 is ON.
D. Activating the Door Strike Relay
Anytime the house phone is connected to the entry phone, the tenant can actuate the door strike by entering the door
strike command on their touch tone keypad. The C-250 determines if the touch tones are coming from the house phone
or the entry phone and only accepts commands from the house phone. Once a valid command is detected, the door
strike relay will actuate for the amount of programmed Door Strike Activation time. If an invalid command is entered,
wait a few seconds and try again. The C-250 will wait 3 seconds after any touch tone entered to assure no more tones
are coming, then it looks for a command match. The C-250 can be programmed to handle either a 1 digit or 2 digit Door
Strike Command (position #41). If a single digit is being used, the minimum touch tone length is 100 milliseconds.
During this time the C-250 must determine if the touch tone is coming from the entry phone or the called party. If the
C-250 is having trouble detecting touch tones from a remote phone because the tones are too fast, use a 2 digit door
strike command. When using 2 digits, the touch tones can be as fast as 50 milliseconds, but the entry phone will be
dropped after the first digit is detected. The C-250 can then be sure that the touch tones are coming from the called
phone.
